Abstract

Compositions for improving plant health, the compositions comprising at least one water-soluble pesticide and at least one non-herbicidal water-insoluble agrochemical, are described. Also described are processes for preparing the compositions and methods of improving agronomic crop plant health using the compositions.

First claim

What is claimed is:

1. A suspension concentrate composition comprising water and at least one water-soluble pesticide in solution therein, a surfactant component comprising at least one surfactant, and at least one water-insoluble agrochemical,
wherein,
the weight ratio of the surfactant component to the water-insoluble agrochemical is from 1:1 to 5:1,
a first portion of the water-insoluble agrochemical comprising at least 10% by weight of the water-insoluble agrochemical is present as a solute in the surfactant component and a second portion of the water-insoluble agrochemical is present as a solid particulate,
the water soluble pesticide concentration is at least 400 grams active equivalent per liter of the concentrate composition; and
the composition does not contain an organic solvent.

2. The composition of claim 1 wherein the water-soluble pesticide concentration is at least 450 grams acid equivalent per liter.

3. The composition of claim 1 wherein at least 20% by weight of the water-insoluble agrochemical is present as a solute in the surfactant component.

4. The composition of claim 1 wherein at least 50% by weight of the water-insoluble agrochemical is present as a solute in the surfactant component.

5. The composition of claim 1 wherein the water-insoluble agrochemical concentration is from about 0.1 to about 20 percent by weight active equivalent per unit weight of the suspension composition.

6. The composition of claim 1 wherein the weight ratio of the water-soluble pesticide on an active equivalent basis to water-insoluble agrochemical on an active equivalent basis is from about 1:1 to about 100:1.

7. The composition of claim 1 wherein the weight ratio of the water-soluble pesticide on an active equivalent basis to the surfactant component is from about 1:1 to about 20:1.

8. The composition of claim 1 wherein the water-soluble pesticide comprises at least one herbicide.

9. The composition of claim 8 wherein the water-soluble herbicide is selected from the group consisting of ALS or AHAS inhibitors, EPSP inhibitors, glutamine synthetase inhibitors, synthetic auxins, Photosystem I inhibitors, ACCase inhibitors, derivatives thereof and combinations thereof.

10. The composition of claim 1 wherein the water-soluble pesticide comprises at least one water-soluble herbicide in the form of a salt selected from the group consisting of glyphosate, dicamba, 2,4-D, MCPA, glufosinate and combinations thereof and the water-insoluble agrochemical is a fungicide selected from the group consisting of bromuconazole, ipconazole, metconazole, tebuconazole, picoxystrobin, and pyraclostrobin.

11. The composition of claim 10 wherein the water-soluble herbicide is a glyphosate salt.

12. The composition of claim 1 wherein the water-insoluble agrochemical has a molecular weight of from about 100 to about 600 grams per mole and a melting point of from about 45° C. to about 110° C.

13. The composition of claim 1 wherein the water-insoluble agrochemical is selected from fungicides, insecticides, herbicides, derivatives thereof and combinations thereof.

14. The composition of claim 13 wherein the water-insoluble agrochemical is selected from the group consisting of triazoles, strobilurins, acylamino acids, pyrimidines, pyridines, arylphenyl ketones, amides, benzanilides, imidazoles, dinitrophenols, morpholines, phenylsulfamides and organophosphorus, derivatives thereof and combinations thereof.

15. The composition of claim 14 wherein the water-insoluble agrochemical is selected from triazoles and strobilurins, derivatives thereof and combinations thereof.

16. The composition of claim 10 wherein the water-insoluble agrochemical is tebuconazole or pyraclostrobin.

17. The composition of claim 1 wherein the surfactant component comprises at least one surfactant selected from the group consisting of cationic surfactants, nonionic surfactants, anionic surfactants and amphoteric surfactants.

18. The composition of claim 17 wherein the surfactant is selected from the group consisting of amidoalkylamines, alkoxylated tertiary amines, alkoxylated quaternary amines, alkoxylated tertiary etheramines, alkoxylated quaternary etheramines, alkyl amine oxides, alkylpolyglucosides, alkoxylated alcohols, phosphate esters and siloxanes, and combinations thereof.

19. The composition of claim 1 containing no effective amount of a suspension aid.

20. The composition of claim 1 consisting essentially of water, the water-soluble pesticide, the surfactant component, and the water-insoluble agrochemical.
